Defence- or war-ships are complex platforms with a number of interdependent systems and subsystems.
As a consequence, the Navy, governmental agencies and system designers have to deal with a large range of variables and parameters; moreover, most of the different military specified variables also have a significant effect on how the system will perform or not.
New designed or midlife converted warships are made-to-order products. This forces the user, the project management and the team of designers to combine and harmonize a large amount of different partly controversial requirements, specified and progressively tightened by naval authorities. In case of electric/electronic systems on board the overall objective of the work is to intervene the different modules in most cases by cables.
All major NATO members independently have tithed rules on Navy cables with respect to toxic and hazardous byproducts in case of fire, cross linking, shielding efficiency, cross talk, wire identification etc. Non of the military specifications are the same.
